Results from every automatic run of the model in WaterSight are saved in this page and can be downloaded by the user for further analysis using WaterGEMS or WaterCAD. Each row of the table lists one complete run of the model. The respective model with the results can be downloaded by clicking in the icon button located on the left of each Model Domain. The frequency at which each model run is saved depends on the run frequency defined in the Numerical Models configuration page.
Model Domain
Automatic name generated by the software once a hydraulic model is uploaded through the Numerical Models configuration page.
Type
Model input format. For now it is only possible to upload WaterGEMS models.
Start Date
Corresponds to the time the model was computed.
End Date
The time for which a new model run will be calculated. This depends on the run frequency defined in the Numerical Models configuration page.
RunTime (min)
The time it took for a complete hydraulic model run.
Status
Shows if the model was computed with success or not. If green the model computed successfully. If orange warning symbol, the model run with success but with some warnings. If red, there was an error and it was not possible to run the model, therefore the latest model results will not be available in WaterSight.
Message
Warnings and error messages are displayed in the Message column.
More detailed information and messages for each model run can be found by downloading and opening the logs file:

Common Error Messages
Failed to obtain zone pattern
Most critical and common error messages will be summarized under Message column as mentioned above. For more detailed message errors the user should download the model run which had problems and download the simulation and log files.
Inside of the downloaded zip file open the UNS file extension and look for an extensive detail of all possible errors and warnings, example below.
A very common error is related with a failure obtaining the zone pattern:
Error: PrepareAdditionalConditions - Failed to obtain zone pattern of zone North
This situation happens when the automatic zone demand adjustment option is enabled for that zone (configured in the Administration >> Numerical Modelling >> Configuration) but there are no flow patterns available for that specific zone.
When that happens the solution is to go to Administration >> Numerical Modelling >> Configuration, edit the existent model by clicking in the row, and in the right side panel remove the zone that is failing from the Adjustment zones option, as shown below. After saving, wait for the next model run (based on the run frequency defined) and check that there are no more errors in the Previous Simulation tab.
To check if the zones have flow data to calculate the patterns that are used in the model or not, please follow the below steps:
1 - Go to Network Monitoring >> Graphs
2 - Select the Zone Overview Dashboard, by clicking in the zone button located on the top right of the page
3 - Click in the zone graph you want to analyse (in the title). This will enter in the zone graph detail.
4 - In the zone graph detail change the pattern option to last month and check if pattern (grey band) gets displayed or not in the graph. If the pattern last month is not displayed, than it will not be also possible to use for the hydraulic model run and the model run will fail in case it is using this zone to adjust the demands.
5 - Sometimes patterns for last month are not being calculated just because there is one or more events happening last month that have the option "Exclude from Pattern" activated. If that is the case, just go to each event and disable the option "Exclude from Pattern" or delete the events.

Execution Failed - Invalid Tank operating range
If the model fails with the message Invalid Tank operating range, this means that value assumed by the hydraulic model for the tank operation is below the minimum or above the maximum. Example of the error message below:
In case you have in the WaterGEMS model the sensor levels as SCADA elements and mapped to tank model elements, most likely that one of the sensor levels values started to register wrong or bad data, which is being used as boundary conditions for the model runs.
In WaterSight go to the tank levels overview page and look for the level sensors that started to measure out of range. Once identified, go to the administration and mark those sensors as offline. Once marked as offline, that sensor will have no more data, and after few hours the new hydraulic model runs will not use the measurements from that specific sensor to override model results. Once the sensor has good data again, don't forget to return to the administration and remove the offline status, so it can start again to be used by the hydraulic model. More information can be found here - Unassigning sensor from model element.
In case you don't have any sensor levels mapped to the tank model elements in WaterGEMS, then the initial tank level value configured in the WaterGEMS model that was uploaded in WaterSight should be wrong, and this should also cause the model to fail while running in the WaterGEMS software.
